Get the advantages of both a hard tonneau cover and a soft tonneau cover for your vehicle with the Revolver X4s. This hybrid tonneau likely has an identity crisis. It's built like a hard cover, but it looks and acts like a soft cover. With the Revolver X4s, you get the strength, durability, and security of a hard tonneau and the sleek look and convenience of a soft, roll-up tonneau - all while protecting your truck bed and cargo and helping to improve your fuel mileage.


The X4s has the features of the original Revolver X4 with upgrades including a matte black aluminum underbody, integrated safety slat caps, rear corner caps, and an integrated bulkhead seal.


Strong, Convenient Hybrid Design

Fully installed coverPartially rolled up cover

The secret to the Revolver X4s's versatility is the aluminum slats on the underside of the cover that make it strong, seamless, and flexible. These individual, hinged slats give the cover its rugged body, while also allowing enough flexibility for the cover to be rolled up. Atop the slats is a tough, 1-piece vinyl layer that adds to the tonneau's sleek look and overall durability while also keeping the slats perfectly aligned. As a result, the Revolver X4s will roll up evenly every time, unlike ordinary soft vinyl covers that can get lopsided as you maneuver them.


Low-Profile Appearance

Cover sits flush for a low-profile appearance

Unlike other tonneau covers that sit 1/2" or more above your truck bed rails, the Revolver X4s sits nearly flush with your rails for a clean, ultra-sleek look.


Full Truck Bed Access

Cover rolled up for full truck bed access

The Revolver X4s gives you full use of your truck bed in a matter of seconds - just roll up the cover and secure it behind the cab. As a result, you can tote around all your gear without having to remove the tonneau. And because the Revolver X4s mounts inside your truck bed rails, you can still use your truck bed stake pockets to mount accessories like tie-down anchors.


Simple, One-Person Operation

Cover is closed and secure

The Revolver X4s is simple to operate. Following installation, just roll the cover out and press down on the rearmost slat at the tailgate to secure the tonneau in place. The built-in latches not only lock down the back end of the tonneau, but they also fasten the sides of the Revolver X4s along the length of the frame rails. The rail tooth runs the entire length of each frame rail. It rotates downward to lock the side rail into the sides of the cover.


Cover is latched closed

When the cover is rolled out and the rear slat is pressed down at the tailgate, the latches on both sides engage. When this happens, the integrated teeth pivot down and rest on top of each slat of the rolled-out cover. Closing the rear slat effectively pins the cover to the rails, ensuring that the cover stays closed from front to back. It's that simple - no Velcro to seal or snaps to wrestle with. When your tailgate is closed and locked, no one will be able to get through the cover, thereby safeguarding your truck bed and its contents. The cover automatically secures as the locking levers at the tailgate engage. These sturdy levers have reinforced gussets that give them added strength and durability. And they will never need adjustment.


Cover unlatched and partially unrolled

To roll up the cover, unlatch the rear slat by dropping the tailgate and pulling either of the 2 release cords located along the bottom corners of the slat's housing. Either cord will release both of the latches so that you can raise the rear slat. When the latches are disengaged, the teeth roll back into the frame rails, releasing the sides of the cover so that you can easily roll it up. Just fold the rear slat over and roll up the cover the rest of the way.


Rolled up cover secured to end of cab by buckle straps - from aboveRolled up cover secured to end of cab by buckle straps - from below

Then secure the tonneau behind the cab with built-in nylon straps and sturdy plastic buckles. These straps help to keep the bundled tonneau from contacting your cab while you drive. And 4 rubber bumpers act as cushioned barriers between the cover and your truck cab.


Heavy-Duty Construction

Heavy-duty, aluminum construction under matte black vinyl

The Revolver X4s's rugged aluminum and vinyl construction makes it an ideal match for your truck, no matter what you do while at work or play. This cover is strong enough to hold up to 400 lbs of evenly distributed weight when it's rolled out. The 1/4" thick, aircraft-grade aluminum slats are covered with a matte black vinyl skin for superior resistance to impacts, UV rays, and weather. This skin is what gives the tonneau its soft, sleek look. While the Revolver X4s may look like a soft cover, its aluminum skeleton provides exceptional security because it cannot be cut through in the same way that a standard soft vinyl cover can be.


Cover lays atop protective felt strips

Felt strips on the underside of the tonneau help to keep the slats from scuffing the vinyl top as you roll up the cover. The soft felt also shields your hands when the cover has gotten hot or cold. And rubber strips overlay your truck's side rails, cab rail, and tailgate, creating a seal that helps to conceal any gaps and works to prevent water from seeping in.


Easy, No-Drill Installation

Clamp-on installation

Installing the Revolver X4s is simple. All you need is a wrench, and you don't have to do any drilling. The tonneau's frame rails clamp to the inside of your truck bed side rails to create a base for the cover. The included bolts secure the front hinge rail to the frame rails at the cab.


Slotted brackets at the ends of the tonneau side rails allow the bolts to shift in case you need to adjust the cover to achieve a snug fit. These brackets ensure proper alignment of the tonneau frame on your truck bed side rails. This eliminates trial and error in installing your rails - you won't have to put them on and then take them off again to get the correct fit. Pre-installed shims and spacers also help to ensure that the Revolver X4s rails are installed squarely on your truck bed.

Easily installed. Meets all expectations. Already recommended to a few people.

love the cover no leaks easy to roll up when you have big loads easy to roll back and fasten. love it.

I have been very happy with this cover. It has been secure and keeps most water out when it rains. It is holding up very well.

I love this cover! It is well made and I was able to install it in 20 minutes. After a year it looks brand new and I've had no issues with it.
Thanks Lisa D for recommending this cover!

GREAT PRODUCT. I LOVE IT!

Very easy to install. Package arrived e arly.

Carrie’s customer service and the products. I’m gonna be a repeat customer.



by:

The cover has held up well, I would purchase again. A couple small items could be updated from the factory but overall its a nice cover.



by:

I saw mixed reviews but took the chance and I regret it! The felt on the inside came off and has made the cover hard to use ripped off only a few short months after I got it. The company sent replacement felt which is going to be a major pain to replace. It also only does an “ok” job at keeping out water. It’s not a single hand open using the wire like it says. Only advantages is that it rolls up to keep majority of the bed open and you can set some stuff on it.



by:

I like that it has the aluminum to keep it a little sturdier than other roll up covers. But I do not like that it leaks by the tailgate and at the top corners close to the cab.



by:

It was easy ti install. I had it for a year and it still looks new. The only thing it needs is a seal for the tail gate. But it only leaks when seating still the rain blowing at the back of the truck or going thru a car wash. Would recommend it, the leak has never given me a problem.



by:

Works great! No issues.



by:

The top is very nice looking and the installation was very easy. The product was engineered well to fit my truck beautifully.
Two issues though...it came with some minor scratches and it leaks at the front corners.



by:

Best roll up tonneau cover on the market. Pairs perfectly with my Thule ladder rack.

  • Ladder Rack and Tonneau Cover Recommendation for 2024 Ford F-350 Long Bed
    Hey Brian, the best tonneau cover and ladder rack combo we have for your 2024 Ford F-350 long bed would be with the Bak Revolver X4s tonneau part # BAK49ZR and the Thule TracRac sliding ladder rack part # TH43003XT-000 this is one of very few options we can guarantee will fit together that will give you a really nice and secure tonneau cover and a very solid and versatile ladder rack.

  • Sliding Thule TracRac Ladder Rack and Tonneau For 2019 Ford F-450 Long Bed
    Yes, Thule does have a sliding SR TracRac that fits your 2019 F-450 long bed with the part # TH43003XT-000 I just checked with them to confirm. Then for a roll up tonneau you'd need the BAK Revolver # BAK49ZR and you'd be set. This is only option currently that fits with TracRac ladder rack as well.

  • Will The BAK Revolver X4s for a 2023 Ford F-350 8' Long Bed Cover The Front Portion Of Bed Only?
    The BAK Revolver X4s Hard Tonneau Cover # BAK49ZR which fits your 2023 Ford F-350 8' long bed has to be in either the fully rolled up or fully covered position. If you go with a cover like the BAKFlip MX4 Hard Tonneau Cover # BAK48331 you will be able to have the panels folded up on the front of the bed partially covering your bed.

Although the BAKBox 2 has not been tested for compatibility with the RetraxPRO MX Hard Tonneau Cover for your 2017 Ford F-350 long bed, part # RT80384, from what I can see, it's highly unlikely that they would work together.

  • TracRac Ladder Rack and Tonneau Cover that Fits 2017 Ford F-250 Long Bed
    I have an option that will allow you to fit a Thule TracRac ladder rack on your 2017 Ford F-250 but you have to go with the sliding TracRac ladder rack part # TH43003XT-000 that you referenced as it fits through the top of the truck bed rails and allows clearance for a tonneau to fit. Now the only tonneau cover we know fits and clears well with this rack is the BAK Revolver part # BAK49ZR as it's rail system is far enough to the inside of the bed rails that it can roll up without interfering...

  • Best Tonneau Cover for a 2022 Ford F-250/F-350 for 5th Wheel Towing
    The BAK Revolver X4s Hard Tonneau Cover is a great option for trucks with fifth wheel hitches as you can secure the cover at the cab when towing, the cover sits flush to the bed so there won't be clearance issues with the hitch when closed, and it has a hard shell so it will provide security with the tailgate shut and locked. It also rolls up like a soft cover for ease of use. The correct one is part # BAK99ZR for 6-3/4' beds or part # BAK49ZR for 8' beds.

  • What Ladder Rack will Work with the BAKFlip MX4 Hard Tonneau Cover on a 2018 Ford F-350
    I do have options for you but the Thule TracRac SR Sliding Truck Bed Ladder Rack part # TH43003XT-000 won't work with the BAKFlip MX4 Hard Tonneau Cover part # BAK48331 on your 2018 Ford F-350. The reason for this is because the uprights on the ladder rack are angled inward and the folding slats on the MX4 would come into contact with the uprights when lifted. You may be able to open the first slat if you moved the rear upright all of the way forward but this is surely not ideal. Instead,...

  • Will BAK Revolver X4s Work on 2017 Ford F-350 8' Bed with Steel Ramp Plate on Tailgate
    In order to use the BAK Revolver X4s Hard Tonneau Cover part # BAK49ZR on a 2017 Ford F-350 with 8' Bed we would have to recommend you remove the ramp plate. Unfortunately, neither we nor Bak has tested this cover with the ramp plate. It's possible you can nudge the cover more towards the cab for clearance but this also means there could be a gap to let water in.

  • Recommended Tonneau Cover For A 2012 Ford F-350 With Fuel Tank Tool Box
    Base on the pictures of your fuel tank/tool box it looks like the lid sits level with the bedrails of your 2012 Ford F-350 so the BAK Revolver X4s Hard Tonneau Cover # BAK49ZR is going to sit too low to be compatible. The aluminum backing will also roll up too large for you to open the lid on your tool box. Instead I recommend the TruXedo Deuce 2 Soft Tonneau Cover # TX769601 which will sit above the bedrails and will roll up to allow you to hook up your fifth wheel and use the rear hinge...

    Not every cover uses a styrofoam filler so it's really dependent on the materials used and the overall quality of the cover. Styrofoam can absorb water though so what you heard isn't untrue. Since you'll have a trailer hitch in the bed the easiest option would be to either use a roll-up or retractable cover to avoid having any issues with the cover being in the way while hauling your trailer. If you'd like a roll-up style then the BAK Revolver X4s Hard Tonneau Cover # BAK49ZR would be...

  • Can BAK Revolver Tonneau Cover Fit Ford F-250 with TracRac SR Ladder Rack
    Yes, the BAK Revolver X4s is actually the only tonneau cover that fits your 2023 Ford F-250 with the Thule TracRac you have because it rolls up narrower than the base rails of the ladder rack. So if you have a long bed truck you would want the part # BAK49ZR or if you have a short bed truck # BAK99ZR. You should be able to install the cover with the ladder rack installed but it would be easier if you removed it.

    The correct Thule TracRac SR sliding truck bed ladder rack for a 2018 Ford F250 long bed is part # TH43003XT-000. I've linked to a product demonstration/install video showing the rack being installed. The TracRac SR ladder rack has generous 1250 lb capacity so you'll likely run out of stuff to put up there before you run out of capacity. The rack uprights can be slid fore and aft to adjust for all kinds of different length loads. One really convenient feature- the sliding rails sit completely...

  • Best 2023 Ford F-350 Long Bed Tonneau Cover for Gooseneck Towing and 3rd Brake Light Camera
    The absolute best tonneau cover for your 2023 Ford F-350 Super Duty long bed is the BAK Revolver X4s: - BAK Revolver X4s Hard Tonneau Cover # BAK49ZR This is by far my favorite cover to recommend because it combines the sleek look of a soft cover with the durability of a hard cover as it's a roll up cover with aluminum slats. This means that you get security when your tailgate is locked, a good looking cover, plus your 3rd brake light camera won't be obscured when this cover is rolled up.

  • How Much Space Does BAK Revolver X4s Take up at Front of Truck
    The BAK Revolver X4s Hard Tonneau Cover, short bed # BAK99ZR or long bed # BAK49ZR, measures about 8" when rolled up. It doesn't roll up completely up to the front so it will probably hang over the bed about 9" or 10" so you'll want to take that into account with your toolbox. Please note that it your toolbox spans the entire width of your truck bed then you may have trouble opening it with any tonneau cover installed due to the rails that will be sitting inside the bed rails.

  • Ladder Rack & Tonneau Cover Compatible With 2018 Ford F-450 Super Duty
    While we have an option for a ladder rack and tonneau cover that fits your 2018 Ford F-450, there isn't a tonneau cover that will work with a rack that mounts inside the bed rail. The reason for that is all tonneau covers either use or sit up against the bed rail when installed, so there would be interference with a rack. The best option is going to be a ladder rack that mounts on top of your F-450's bed rail, and a tonneau that mounts inside the rail. For the rack, what you will need...

    Since we do not carry the Adarac Extreme Mid Height Triple Crossbar Rack and since we do not know exactly how the rack installs, we cannot confirm with absolute certainty that the Bak Revolver X4s # BAK49ZR (BAK 80331) works with the cover on your 2018 Ford F-350 Super Duty with an 8-foot bed. Judging by the photos, though, the rolled-up cover most likely will interfere with the mid-height bars of the rack. Also, the X4s only works with ladder racks that install directly into the stake...

This can vary as the cover often sits for oblong than a perfect circle. The 8" diameter you have seen is found on short bed trucks. And the cover can only be secured either in the fully rolled up or laid out position. There is no way to secure it partially unrolled. But as you have the Auto-Slide hitch it will ensure you...
